[SOLVED] Can't start xmonad

Enrico1989 · 2023-11-04 09:49:27

I installed xmonad via

sudo pacman -S xmonad

and creating an ~/.xmonad/xmonad.hs file with this content

import XMonad

main = xmonad def
    { terminal    = "urxvt"
    , modMask     = mod4Mask
    , borderWidth = 3
    }

but trying to start it from a console via either of

$ xmonad
$ xmonad --recompile

gives this error

XMonad will use ghc to recompile, because neither "/home/enrico/.xmonad/build" nor "/home/enrico/.xmonad/stack.yaml" exists.
XMonad recompiling (forced).
Errors detected while compiling xmonad config: /home/enrico/.xmonad/xmonad.hs

xmonad.hs:1:1: error:
    Could not find module ‘XMonad’
    Use -v (or `:set -v` in ghci) to see a list of the files searched for.
  |
1 | import XMonad
  | ^^^^^^^^^^^^^

Please check the file for errors.

xmonad: xmessage: executeFile: does not exist (No such file or directory)

Looking on the web and on this forum, I have the feeling that something is wrong because

ghc-pkg list | grep xmo

results in no match, and that I could probably fix that by

cabal install --lib xmonad

but before even trying htat, I'm wondering why am installing xmonad both via pacman and via cabal? After all, the doc page doesn't even mention cabal.

Make sure to not have run partial updates at any point - haskell is hyper-fragile.

Executing

ghc-pkg recache

with and without sudo and then trying again

xmonad --recompile

ends up with the same error.

After all,

ghc-pkg listi

still gives no xmonad match:

On the other hand, it's not clear how the asker originally installed xmonad. Maybe they did use cabal/stack as suggested in xmonad installation guide?

Not sure... I've used ghcup tui to update GHC, cabal, and HLS to the most recent recommended versions, this morning.

Looks unsuspicious

ghc is /home/enrico/.ghcup/bin/ghc

I assume in the second and third commands you meant ~/.xmonad/xmonad.hs as the argument to --make, in which case

.xmonad/xmonad.hs:1:1: error:

The custom ghc in your $HOME is your problem.

Enrico1989 · 2023-11-04 18:42:11

I don't think I've intentionally done anything for it to be there. Probably that's where the executable is put when managing Haskell installation via ghcup, I guess.

Why is that my problem? What is wrong with the executable being there? Where should it be (I assume it would be there if I had set up my Haskell env via pacman -S ghc instead of via ghcup)?

Enrico1989 · 2023-11-04 18:43:19

I guess the bottom line is "if you install GHC via pacman, install xmonad via pacman, whereas if you install GHC via ghcup, install xmonad via cabal/stack"?

seth · 2023-11-04 20:39:12

The problem is that the local ghc installation doesn't know about the xmonad modules - why would you have *additionally* installed ghc via ghcup?

If you want to keep it for special occasions, make sure that /home/enrico/.ghcup/bin is only in your $PATH for that purposes - not generally.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

What do you mean?

That I have done that and I shouldn't have?

You've ghc installed via pacman, why do you (think you) require an additional ghc version?

Enrico1989 · 2023-11-04 20:58:30

I remember the reason I installed ghc via ghcup is that the latter lists many version telling which one is hls-powered, which is kind of necessary for haskell development (command completions, diags, ..).

Why I also have the ghc installed via pacman... well that's probably a remnant of before I installed ghcup.

Can I do without the pacman-installed ghc and just use the one installed via ghcup?

Is this the answer?

Given the API instability of haskell: probably no if you want to use the repo version of xmonad - you'd have to install that using, I assume, ghcup as well - whether you can use cabal/stack, idk.
